Question about Toyota Avalon

1 Answer

I have a 1997 Toyota Avalon. Often the engine will be running fine, and then it just starts running rough, like it's missing on a cylinder. If I turn it off and let it sit for maybe an hour and try starting it, it will run fine again, until it happens again. Thank you.

A miss like this can be due to more than one thing, it sounds like there is a definite from what you are saying this can be due to vehicle in need of a tune up especially bad spark plugs. It can also mean that you have a bad inject or bad injector wiring. Check wiring with a NOID light(light should have a steady/constant Ficker). Conatct if you need more help. Good Luck thanks for using FIX YA

01 toyota avalon with codes PO300-306 car runs rough and idles rough now while driving it start loosing power and making a snake rattling sound


Is the rattling sound coming from the exhaust? I'm wondering if perhaps you have a loose catalytic converter. P0300 (multiple cylinder misfires) and P0306 (cylinder #6 misfire detected) are probably the cause as to why the car is sluggish, shakes, runs rough and lacks power. Make sure to take a close look at your ignition system (spark plugs, ignition wires, coils...). A spray bottle filled with soapy water can help you find voltage leaks on the wires and coils. Just spray the wires and coils and look for arcing. Replace any component that arcs. Other causes can be fuel injectors, vacuum leaks...).

I have a 2007 Toyota Avalon. The check engine light turned on and around forty minutes of driving it, it starts to run rough. I replaced the gas cap with a new one. I thought this would solve the...


A flashing check engine light indicates a cylinder missfire. A evaporative emissions leak (the result of a bad gas cap) wouldn't cause a rough running condition. How many miles are on the vehicle?

1997 3.4l 4runner misses at idle when first start


The coil packs on these engines will show signs of Arc tracing. Its a white shadow or line that runs along the rubber boot. if you see this. Suspect that coil of grounding and causing a misfire. Misfires usually occur after an electrical part is hot, the rough idle for the first 30 seconds sounds like another issue altogether, especially if it goes away after 30 seconds. Misfires from coils dont usually go away,,,,, they just get worse. Good luck . I also use this forum for my Toyota truck issues, I own one with the 3.4. heres the link http://www.tacomaterritory.com/forum/
